Answer:

725 - 360 = 365

365 - 360 = 5

The acute angle is 5 degrees.

sin2θ = sin(2*5) = sin(10) = 0.1736

X+9=2x-3<br> FIND THE X!!!!!!
Ierofanga [76]

Answer:

x = 12

Step-by-step explanation:

<u>To find "x"</u>, we need to <u>isolate it</u>. This means move "x" to the left side, and everything else to the right side.

When moving a number, do its <u>reverse operation</u> to the entire equation.

x + 9 = 2x - 3

x - 2x + 9 = 2x - 2x - 3         Subtract 2x from both sides

-x + 9 = -3                              

-x + 9 - 9 = -3 - 9           Subtract 9 from both sides

-x = -12

-x/-1 = -12/-1          Divide both sides by -1 to get rid of the negatives

x = 12                     Final answer

Check your answer. Split the equation for the left and right sides. Substitute "x" for the answer "12".

LS:   (left side)

x + 9

= 12 + 9              Add

= 21

RS:   (right side)

2x - 3

= 2(12) - 3            Multiply before subtracting

= 24 - 3               Subtract

= 21

Both sides equal to 21 when "x" is 12.

LS = RS          left side equals right side

Therefore the answer is correct.
